Fat Fapping

To watch your arm jiggle while you masterbate.

Hey what did you do last night? "Fat Fapping" you mean when you stare at your arm while you masterbate? Yupp.

Fat Fap

The act of wrapping your stomach fat around your penis and fapping with it.

I caught that Bill guy fat fapping the other day. Gosh he's fat.
